It); all whom it may concern:

Be it known that I, LOUIS 'Fnm), a citizen of the United States, residing in Philadelphia, Pennsylvania. have 'invcntcrl certain. Improvements: in. Roller-Screens, cl? ivhich the following a specification.

My invention relates to roller screens,

more particularly screens of the type cm ploying a metal housing which is carried by the window frame nlndsupports a spring roller upon which i: he screen is wound; the material of such screen being of flexible metal or fabric and capable of being Wound up upon. the spring roller.

In the pic-sent invention, my improved screen structure comprehcnds casing or housing to be attached to the window sill, and re trelly mounted with respect to the mama. mensions of the window frame: si'lch on: gr having end Walls in which a spring roller, upon which the screen is wound is opereti i'ely mounted. Carried by the Sides of" the Window frame are metal gniding'memhers receiving the edges of the screen; said guiding members being double- Wnlled throughout their length for the re cc'ntion of the screen fabric and having enlarged sockets adjacent the sill for the receptlon of the ends of the oiler housing or and other features of my invention r fully described. hercii'iefter, refer ence hei lied to the accompanying drewinffs. in. hich:

The housing is provided with end walls 8 and 8 inlegrnl tl'ierewith in which the spring roller is opcrntivcly mounted, and such casing is preferably secured by means of fastening members 9 passing through the bot- ;tom of the some into the sill.

For this purpose, it may be provided. with a pair of keyhole slots; 11, for engagement with hooks ll" carried by the sash in the manner clearly slum-n in the drawings.

In order that my improved screen may be employed with windows of varying width, I provide side guides 12 for the edges of the screen, which guides are quite wide so as to receive a greater or less portion of the screen and the casing for the spring roller. These guides are sittnchaliile to the sides of the window frame and are provided with enlarged portions or sockets 13 to receive the ends of the roller l'lOHSlL It will he noted that the roller housing 5 complete in itself having end Walls-8 and H in which the roller is opcrativcly mounted; the Wall 8 being apertnred to receive the spindle 3 While the Wall 8 is slotted to rw' ivc the squared tensioning shank (5 The side guides comprise double-Walled metal strips; the walls 12* of which are sipnccd apart for the reception of the edges of the screen, While said double walls are doubled he cl: at the rear to I'JIOYlflG a flanged (I'llilfi'l. l4- ivhercbr tl-mrmny he eccurcd to the eidc of the Window frame; such portion lie" nterior-inserted o ipcrtnrcd at 15 for the rcw til'm of fastening moons in. the nature of Fcrcws. nails. &c., 16, while the lower ends leash and 1 My ance,
